Hoping someone can tell me how to contact Yvonne Smith (Mrs. Dan A.) who was residing in Aiken, SC when her mother, Mary Helen, died there in 1989. The father, Russell Hiday, died there in 1986. A WWII buddy of Yvonne's brother, would like to make contact with Yvonne or her children. We have been unsuccessful in our attempts to locate Yvonne to date.
